Unformatted text preview: initial velocity , the final velocity , the acceleration due to gravity and the time . Substitute and solve for . Thus the final and initial velocities of the ball are equal in magnitude. In other words, the speed with which the ball is thrown up is equal to the speed with which the ball comes back down to the starting point. The negative sign indicates that the velocities are in opposite directions. http://www.hwproblems.com/cgi-bin/book.cgi?bookid=0044&cptn=2pr41&id=62762 [1/31/2008 12:13:56 PM]...
